Hmm, could we handle this more elegantly? At the very least, we should probably try to keep the labels as an attribute, so that you have the option of doing something constructive with them afterwards. Perhaps we need an entire new data class (say "labeled") and an as.factor() method doing basically what happens now.

BTW, I take it that you mean "when there are values with no labels", not "labels for values that are not present in data", right?
